    Well first things first. I gotta get that wheel in and the bearing preload set. Then we chase the smoke.

    Ok So I put the wheel all back together and greased everything like it said to. I ran the nut tight as instructed to check the preload and there was the tiniest bit of movement when I did the shake test. I took out the axle and measured the wedding ring spacer. It was .271" thick. So I lapped it on a glass plate with 220 grit sandpaper to .2695". put it back in and I had less movement during the run up but enough to pull it back out for a little more lapping finishing it with 600 grit for a finished thickness of .268". In it went preload is set to as movement free as I can stand at this point. Now to adjust that rear brake actuator arm back a spline. Then a carb look see and rebuild.

    Easy test to point to valve guides...
    at night when stopped at the lights just idling...with a car behind with their lights on, as you accelerate check the mirrors. If you see lots of smoke thru the back-lighting and it dissipates after a 100 metres or so will suggest valve guides as a problem.

    So this week end I'll rebuild the carbs so I'm at a good starting point for tuning and balancing. Does any one here have a good source for throttle cables?
